OPatch found the word “warning” in the stderr of the make command.Please look at this stderr. You can re-run this make command.Stderr output:ins_precomp.mk:19: warning: overriding commands for target `pcscfg.cfg’/u01/app/oracle/product/11.2.0/db_1/precomp/lib/env_precomp.mk:2160: warning: ignoring old commands for target `pcscfg.cfg’/u01/app/oracle/product/11.2.0/db_1/precomp/lib/ins_precomp.mk:19: warning: overriding commands for target `pcscfg.cfg’/u01/app/oracle/product/11.2.0/db_1/precomp/lib/env_precomp.mk:2160: warning: ignoring old commands for target `pcscfg.cfg’

The database seemed fine, though. I contacted Oracle support just in case, and it was confirmed as a known issue. The document with ID 1448337.1 has more information on it. So basically, these warnings can be safely ignored…
